Features and Benefits

  • High efficiency design with low power consumption

  • Modular system resulting in maximum flexibility to adapt to a wide variety of applications

    • Extensive hydraulic options available to adapt to different process fluids

    • High interchangeability with five casing options on the same power end

    • Four high efficiency impeller options; reverse vane, closed and open impellers available

  • Low maintenance costs due to minimal downtime and maximized uptime

    • External micrometer impeller adjustment mechanism accurately sets impeller clearance in 20 seconds, in the shop or the field

    • Back pull-out design allows removal of rotating element without removing casing, piping or motor

  • High environmental and personal safety during operation and maintenance

  • Heavy-duty casing with integral foot and multi-ribbed discharge flange provides superior resistance to pipe loads and improves reliability

  • Precision cast reverse vane impeller is the only impeller design that offers repeatable pump performance throughout the life of the pump

  • SealSentry™ seal chamber extends seal life and provides advanced self-flushing capability

  • Standard non-contacting labyrinth seals keep lubricant in and contaminants out

  • Heavy-duty radial and thrust bearings selected for long life and reliability

  • Two-piece, ductile iron bearing housing is designed for safety, strength, interchangeability and retrofit capability

  • 1935/2004/EC food grade compliant option

Configurations

CK: Closed coupled model provide a compact arrangement ideal for installations where space is a premium.

N: Centerline mounted, high pressure model is available for applications in which loads caused by thermal expansion need to be reduced.

H: Foot-mounted, high pressure model is the workhorse of chemical plants and other industries with a pressure rating up to 25 bar (365 psi).

P: Unitized self-priming model is engineered to draw from liquid sources below ground level or from sources that have no positive pressure to naturally prime the pump.

R: Recessed impeller model uses vortex action to provide low-shear pumping of friable solids and trouble-free pumping of stringy or fibrous slurries.
